Printrbot Paste Extruder

Brook Drumm of Printrbot posted on his G+ about Printrbot Paste Extruder.
He announced some possible interesting future implementations of this type of extruder:

• Heated syringe (chocolate and human cells??)
• Printable files to convert to dual chamber syringe with quick drying silicone and a mixer nozzle (off the shelf stuff)
• quick setting UV resin paste with light on the end of the tip 
• conversion to a Bowden type setup so the extruder can sit on the table getting all that mass off the printer
• a sister extruder that will push moist clay through a bigger hose for big clay prints ready to fire
• large pneumatically assisted reservoir for longer/bigger prints feeding a screw drive print head
• new material mixes for sturdier paste and firmer clay to support the weight of the print (cellulose, etc)
• metal construction to get rid of laser cut wood 
• dabble in concrete then scale it up
• -ugar paste for edible goodies
• shortbread cookie recipes for cookie paste
• pancakes, anyone?
• 3d jello art
• crazy ideas from the community welcomed here!!
